A race of a bearing assembly is provided. The race includes an exterior facing surface having front and rear faces and serrations extending in an axial direction between the front and rear faces and protruding outwardly from the exterior facing surface.

Bearing race with serrations

A power takeoff unit for an automotive vehicle being a normally front-wheel drive vehicle that is convertible to all wheel drive. The takeoff unit includes an input shaft supported in a housing, the input shaft is torsionally connected with a transmission of said vehicle. An output shaft concentric with the input shaft is provided, the output shaft is torsionally connected with the rear wheels of the vehicle. A shift collar to selectively connect said input shaft with said output shaft is provided. A shift fork is provided to translate the shift collar, the shift fork having a main body with a bore. A cylinder is connected with the housing. A piston is slidably mounted within said cylinder. A headed fastener is provided with a shank extending through the shift fork main body bore. The fastener head engages the shift fork, the fastener's shank being threadably engaged with the piston to capture the shift fork with the piston.

Power transfer unit (PTU) assembly with cylinder

An arrangement of a vehicle is provided having normal transverse engine/transmission normal two-wheel drive operation which can be selectively placed into four-wheel drive operation wherein a pump which powers the coupling or uncoupling is independent of the transmission lubrication pump and is powered by the transmission.

Power transfer unit (PTU) assembly with hydraulically actuated disconnect rear output shaft

A number of variations may comprise a method comprising: a lubrication system for a transfer case comprising: actively managing an oil level in a plurality of sumps in a transfer case by rotating at least one rotating element in the transfer case to transfer oil through the transfer case to lubricate the transfer case.

ECO lubrication method for a transfer case

An arrangement of a vehicle is provided having normal transverse engine/transmission normal two-wheel drive operation which can be selectively placed into four-wheel drive operation wherein a pump which powers the coupling or uncoupling can be positioned downstream of a power takeoff unit without utilization of an electrically powered pump or transmission powered pump.
